SIPHON FOE, .AETED LIQUIDS.

Application filed July 29, 1913. serial No. 781,721.

To all whom it may concern;

Be it known that I, MARTIN, Fmnnnn, a citizen of the Empire of Germany, and a resident of Zeitz, Saxon Germany, have 5 invented certain new an useful Tmprove ments in Siphons for Aerated Liquids, of which the following is a specification.

Thisinvention has reference to a novel siphon for aerated liquids and perta1ns 19 particularly to aerated potable liquids, such as beer, especially lager-beer.

The beer siphons heretofore employed have the defect thatithe tightening ring is provided between the container and the in- 5 sorted glass parts. This arrangement causes that the pressure of the tightening closure is exerted on the outer circumference of the rim of the glass vessel which implies the danger of breaking the glass vessel by the g0 pressure. This danger is increased by the boringin the glass vessel adjoining the upper rim of the same which boring serves for the purpose of introducing carbonic acid g The present invention has for its purpose to avoid the described defects. This has been primarily attained by providing between the outer vessel and the glass container an angular gasket for the purpose of tightening the siphon. The gasket is composed of two parts of which one reaches between the glass container and the outer vessel and secures their relative positions while the other part of the gasket serves for tight- 85 ening the cover.

In order to-render the invention entirely clear reference is had to the accompanying drawing in which:

Figure 1 represents in sectional vertical '40 elevation a siphon embodying in desirable *form the present improvements. Fig. 2 illustrates in longitudinal section, on an enlarged scale, the valve mechanism. Fig. 3 shows in longitudinal section the valve 415 through which the carbonic acid gas is introduced.

Similar characters of reference denote like parts in all the figures In the siphon illustrated on the drawing A represents a metallic outer vessel in which the glass container B is so inserted that it rests upon the curved bottom C of the metallic vessel A. This leaves the upper rims of both, the metallic vessel A and 'the glass container B in approximately the same horizontal plane. Upon the cover D there is the ing the valve spindle the key P serves in the closing valve F which serves as a support for the long glass tube E in which the liquid rises. The cover D further is provided with the valve G through which carbonic acid gas is introduced into the container B. In accordance with the present invention an angular gasket H serves for tightening the device. The gasket H is made of rubber or elastic'material. It is composed of two 5 portions of which the descending portion is adapted to secure the glass container B in its middle position in the metallic vessel A. Accordingly this descending portion solely serves for preventing the glass con .tainer from any disturbing lateral movements. The second horizontal portion of the angular gasket serves for the tightening of the device on the rim portion T of the metallic vessel A. The cover D is placed upon said horizontal portion of the rectangular gasket and secured by means of screws passing through the cover into the rim portion I of the metallic vessel.

The angular gasket H is provided with a small tube K for the purpose of establishing connection between the interior of the metallic vessel A and the space below the cover D. By virtue of this connection the glass container remains from the outside as under a uniform pressure. The provision-of this small tube forming a connecting chan nel also permits of the passage of the gas when the device has been tightened.

The .closure of the long glass tube E, in which the liquid rises, against the discharge tube L is secured in the following manner: The valve spindle M, shown in Fig. 2, is provided at its lower [end with a tightening washer or plate N which rests upon the member 0 below, which member is screwed into the cover and serves as a support for the valve casin When the tightening washer or plate is so selected as to size that it just covers the bottom face of the valve spindle M then the valve spindle may be taken out and the washer N renewed should this become necessary. For tightenusual manner.

The valve G which serves for introducing carbonic acid gas into the container B is screwed into the cover D, as shown in Fig. 3. The valve G is so constructed that the valve seat cannot be clogged or get dirty. For this purpose the body of the valve is provided with a central boring Q which R of the valve. The head R is surrounded by a rubber mantle S which is provided with an opening or boring T in thevcenter of its lower (portion. This discharge openingT is locate on a closed portion of. the valve body, referably opposite the gas inlet channel.

he carbonic acid gas passing through the channel Q must widen the-rubber mantle S considerably for Hermitting of the passage of the gas aroun the edge portion of'the valve body so that the gas may reach the discharge opening T of the rubber mantle S. It is of course evident that the rubber mantle normally presses tightly against the walls of the valve head R to afford a secure closure. The elasticity of the rubber mantle accordingly is subjected to considerable strain during the introduction of the carbonic acid gas, therefore the valve opening T, after release, is closed in a rather enertic manner.

The discharge openings of the valve head B may be provided in other, locations than those shown on the drawing as long as they are sufliciently apart.

I claim as my invention:

1. A siphon for aerated'liquids' comprising a container for the liquidopen at the top at full width, a protective vessel around the container having a top rim portion, a cover, means thereinfor introducing carbonic acid gas and discharging the liquid, and an annular gasket composed of two parts at right angles to each other, a vertical portion between the container and the rim of the protective vessel to hold them in position, and a horizontal portion for securing the cover;

2. A siphon for aerated liquids comprisliquid, and an annular gasket composed oftwo parts at right angles to each other, a vertical portion between the container and the rim of the rotective vessel to hold them vin position, a orizontal portion for securing the cover, and means in said gasket for maintaining uniform pressure within the container and the space between said container and protective vessel.

3. In a beer siphon of the type described, a glass container open at the top at full wi th, a protective metallic vessel around the same having an outward top rim and a cover, in combination with means for maintaining uniform pressure within the container and the space between said container and protective vessel consisting of an. annular gasket composed of two portions at right angles to. each other, a vertical portion for holding the container and protective vessel in position and having means for establishing communication with the container and the space between same and the protective vessel, and a horizontal portion for tightening the cover.
